Disable guardian in passthrough with shared spatial anchors not working

Hello, 

Adding this line to the manifest disable the guardian while in passthrough: 

<uses-feature android:name="com.oculus.feature.CONTEXTUAL_BOUNDARYLESS_APP" android:required="true" />

But for the Shared Spatial Anchors sample from github it doesn't work. 

Here is my full manifest :

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="auto">
<application android:label="@string/app_name" android:icon="@mipmap/app_icon" android:allowBackup="false">

<meta-data android:name="com.samsung.android.vr.application.mode" android:value="vr_only" />
</application>
<uses-feature android:name="android.hardware.vr.headtracking" android:version="1" android:required="true" />

<uses-feature android:name="oculus.software.handtracking" android:required="false" />
<uses-feature android:name="com.oculus.feature.PASSTHROUGH" android:required="true" />
</manifest>

Do you have any idea why ?

Thank you !
